FORT COLLINS, Colo. (AP/CBS4) — The Department of Veterans Affairs says six employees at a clinic in Fort Collins and the VA Medical Center in Cheyenne, Wyoming, should be disciplined for manipulating data about veteran care.

The VA has proposed unspecified action against Rocky Mountain Network Director Ralph Gigliotti and Cheyenne VA Medical Center Director Cynthia McCormack. The department did not specify which other employees are facing discipline.

Acting VA Secretary Sloan Gibson said Tuesday the actions of employees who have been found to have manipulated data will not be tolerated.

“Employees who have been found to have manipulated data, withheld accurate information from their supervisors, and affected the timeliness of care Veterans receive do not reflect VA’s values, and their actions will not be tolerated,” Gibson said in a statement. “VA must earn back the trust of Veterans. Part of earning back that trust is holding people accountable when there is documented evidence of willful misconduct and management negligence.”

Investigators from the VA’s medical branch say workers were told to make their records show that veterans got appointments within 14 days of the day requested, whether or not it was true.
